I don't even remember how this got started but sometime during vacation I found this game for my phone called Match 3D. (There are several version, look for the one specifically called Match 3D) I loved playing it and showed my wife. Now she's obsessed even worse than me.
I'm not sure why it's so addictive but it's fun and makes you forget everything for a few minutes and you actually get better the more you play.
Here, let me show you.
